Just put down a deposit on a 20 plate car but I have since found out it has 3 previous keepers and a plate change. The plate change doesn't worry me, it appears to have been registered with a private plate by the first owner. First owner had it a year, second only about 8 months and the third over 2 years. I'm just a bit worried about the car being unreliable. I've had my current car over 10 years so it's been a long time since I bought a car. I do notice that cars generally seem to have more owners than before but this seems like a lot. Would it concern you?
